This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field
If py2 is not found *and* the compiler is MSVC, we didn't take into
account that py2 is not found. This also meant that we didn't take into
account the expected count when it *is* found, because the python module
has a better finder than just "is the binary on PATH".
msys2 is broken only on clang, due to -Werror issues in the python
headers as patched by msys2.
MSVC is simply weird... due to the use of an unversioned platlib/purelib
directory, the python2 and python3 components overlap.
Perhaps when this test case was originally created, project tests could
not use a matrix of options? This is certainly possible today, so don't
write special unittest handling for this instead.
This adds proper visibility into what gets run and what doesn't. Now we
know which python executables got tested and which got skipped.
